Effects of poly(vinyl alcohol) blending with Ag/alginate solutions to form nanocomposite fibers for potential use as antibacterial wound dressings

The first set of data comprise FTIR spectra of Ca-alginate, Ag/Ca-alginate, pure PVA, PVA/Ca-alginate, and PVA/Ag/Ca-alginate fibers. The fibers were obtained by extrusion and gelation of the aqueous solutions with following compositions: for Ag/Ca-alginate fibers - 1.27 ± 0.08 w/v Na-alginate and AgNPs at 2.6 mM, for Ca-alginate fibers - 1.27 ± 0.08 w/v Na-alginate, for PVA fibers - 5.7 % w/v PVA, for PVA/Ca-alginate fibers - 5.7 % w/v PVA and 1.27 ± 0.08 w/v Na-alginate, and for PVA/Ag/Ca-alginate fibers - 5.7 % w/v PVA, 1.27 ± 0.08 w/v Na-alginate and AgNPs at 2.6 mM.

The second set of data are UV-Visible absorption spectra of the initial PVA/Ag/Na-alginate colloid solution (5.7 % w/v PVA, 1.27 ± 0.08 w/v Na-alginate, 2.6 mM nominal silver concentration) and resulting fibers produced after gelling of alginate after dissolution in 2.28 % w/v sodium citrate solution.

The third set of data are force and stroke values over time measured by using a Universal Testing Machine for Ca-a...
